Abstract

Surface heating subsequent to Pleistocene glaciation in Australia has resulted in a decrease in near-surface thermal gradients.
Heat flow in shallow holes therefore appears to increase with the depths of determination. Some data obtained at depths less
than 300 m may require positive corrections up to 25 percent, depending on the rate of glacier retreat and the amount of warming.
Climatic models formulated for periglacial regions have been generalised for regional use. Surface temperatures are assumed
to have increased by 5°C at 15 000 BP. The primary features of this model have been confirmed, using data previously published
for deep holes remote from regions of glaciation near Kalgoorlie and Broken Hill.
